| Abstract | The hexane, CH2Cl2, EtOAc, CH3OH extracts, and the essential oils from nineteen plants, and 3 selected compounds were tested for preliminary anti-orchid pathogenic microorganism screening on Dendrobium 'Pompadour'. The extracts from Garcinia mangostana, Cinnamomum porrectum and Echinochloa colona showed good tendency to inhibit bacterial disease in orchids. gamma-Mangostin from G. mangostana and the essential oil from C. porrectum revealed the best inhibition against Burkholderia gladioli. Using bioassay-guide, the separation of the CH2Cl2 extract from E. colona yielded an active compound: undecanoic acid. In addition, the essential oil from Zingiber cassumunar and gamma-mangostin showed high potential antifungal activity against Phytophthora palmivora, but showing not good results against Fusarium oxysporum. The in vitro antipathogenic tests in orchid Dendrobium sp. tissue culture revealed that the CH2Cl2 extract from E. colona and gamma-mangostin had good potential to inhibit B. gladioli and P. palmivora, respectively |
